Notes:
This series began during the second wave of DC Comics "New 52" series.
Earth-2 had previously been announced during various online Internet interviews, where its key players were introduced. This series gained fame when it was announced that the first Green Lantern ever, Alan Scott, would be homosexual. This was later confirmed in issue #2.
What is also different about Earth-2, is that on this Earth, other famous heroes like Batman, Superman and Wonder Woman had all died during the first issue, preparing the way for a new generation.
